Fees charged by periodical editors to the authors of papers in regular academic journals approved by the Press and Publication Administration. In the field of domestic general publications, tripolar polarization is charged, but it is relatively easy to happen, and the cost is more than 2000, because most of them start from the third edition, and some can start from the second edition, but there is a risk of being rectified. Publishing is free or nominal, but it is extremely difficult, and some of them are equivalent to the core. The so-called publications can be consulted by the General Administration of Long Yuan, or by periodical websites and HowNet meetings.
